Note:
Button Function Description:
1. Control the backlight
Short press—switch the backlight on and off
2. Set the battery type and number of strings
(1) Press and hold the case for more than 3 seconds to switch to the battery type interface Battery.
In the battery type interface, short press to select the battery type. The battery type can be switched between Pb12V / Li3.7V / Fe3.2V
Pb12V—12V lead-acid battery
Li3.7V—Ternary lithium battery
Fe3.2V—lithium iron phosphate battery
(2) After selecting the battery type, press and hold the case for more than 3 seconds to switch to the battery string number interface number
In the battery string number interface, short press to select the battery string number NS (N represents the number of strings)
12V lead-acid battery—N = 1/2
Ternary lithium battery—N = 2/3/4/5/6/7
Lithium iron phosphate battery-N = 2/3/4/5/6/7/8
(3) After selecting the number of battery strings, press and hold the case for more than 3 seconds to return to the normal interface

Package Includes:
1 x Battery Voltage Point Gauge
